In 2019,Monatshefte fuer Chemie included an article by de Aguiar, Sara R. M. M.; Schroeder-Holzhacker, Christian; Pecak, Jan; Stoeger, Berthold; Kirchner, Karl. Safety of 2,6-Diaminopyridine. The article was titled 《Synthesis and characterization of TADDOL-based chiral group six PNP pincer tricarbonyl complexes》. The information in the text is summarized as follows:
The new chiral PNP pincer ligand N2,N6-bis((3aR, 8aR)-2,2-dimethyl-4,4,8,8-tetraphenyltetrahydro[1,3]dioxolo[4,5-e][1,3,2]dioxaphosphepin-6-yl)pyridine-2,6-diamine (PNP-TADDOL) was synthesized in 80% isolated yield. [M(PNP-TADDOL)(CO)3] (M = Cr, Mo, and W) were prepared via a solvothermal approach. This methodol. constitutes a fast, simple, and practical synthetic method to obtain complexes of that type in high isolated yields. The x-ray structure of the Mo complex is presented. In the experimental materials used by the author, we found 2,6-Diaminopyridine(cas: 141-86-6Safety of 2,6-Diaminopyridine)
2,6-Diaminopyridine(cas: 141-86-6) belongs to pyridine. Pyridine and its simple derivatives are stable and relatively unreactive liquids, with strong penetrating odours that are unpleasant.Safety of 2,6-Diaminopyridine
